According to the system voice command docs, you can open an application with a voice command. e.g. OK Google - open foobar. Also according to the docs, this Works by default; no specific intent.
In my sample development app, this isn't working. I've tried adding a few combinations of action and category permutations to the intent-filter, but no luck so far.
I'm targeting a minimum SDK of 23, testing on a device with 6.0.1.
Should this work, and if so, what are the changes to a new empty activity project I need to enable it?
As far as I am aware, Google simply iterates over a list of installed applications and opens the corresponding application if it finds an exact match.
To test this, use the following Intent
final String PACKAGE_NAME_GOOGLE_NOW = "com.google.android.googlequicksearchbox";
final String GOOGLE_NOW_SEARCH_ACTIVITY = ".SearchActivity";
final String APP_NAME = "Open " +getString(R.string.app_name);
final Intent startMyAppIntent = new Intent(Intent.ACTION_WEB_SEARCH);
startMyAppIntent.setComponent(new ComponentName(PACKAGE_NAME_GOOGLE_NOW,
PACKAGE_NAME_GOOGLE_NOW + GOOGLE_NOW_SEARCH_ACTIVITY));
startMyAppIntent.putExtra(SearchManager.QUERY, APP_NAME);
startMyAppIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
startActivity(startMyAppIntent);
} catch (final ActivityNotFoundException e) {
e.printStackTrace();
}
If this opens your application, then it is simply a case of the phonetics of your application name, or how Google interprets your pronunciation of it.
I do think that there should be an option to add a 'phonetic app label' to the application's manifest (or some other globally available configuration file), so Google could open your application if the unique name is not common enough to generate a voice search result.
If this doesn't open your application, check that you are correctly defining your application name in the manifest as follows:
<application
android:label="#string/app_name"

I'm currently developing an Android application in order to display home screen widgets. Those ones are related to Microsoft Outlook (Events + Messages) in order to show incoming events and unread new messages in a kind of dynamic tiles.
The Msal graph library helps me a lot to authenticate and retrieve in formations which contains an identifier for each event / message results
But now I want to know if the outlook application is installed on the user device and if there is a way to open Outlook when the user click on the widget. Moreover if the user can open the corresponding clicked event or message with the identifier.
For example the Event widget currently displaying a birthday event. The user click on it. Then it opens Outlook and display directly that birthday event.
Regards
I don't think this is officially documented somewhere. But here's what you can do to find out about it.
You can list all Microsoft applications installed on your device...
val packages = context.packageManager
.getInstalledApplications(PackageManager.GET_META_DATA)
for (info in packages) {
if(info.packageName.startsWith("com.microsoft", true)){
Log.d("package name:" + info.packageName)
Log.d("Launch Activity: " + context.packageManager.getLaunchIntentForPackage(info.packageName))
}
}
Take a note of the "launch intent" displayed in the LogCat. You can use that to launch Outlook. Just make sure you don't hard-code those values because Microsoft can change those values at any point, for example the activity class can change. So, instead of doing this...
context.startActivity(
Intent().apply {
action = Intent.ACTION_MAIN
addCategory(Intent.CATEGORY_LAUNCHER)
setPackage("com.microsoft.office.outlook")
component = ComponentName("com.microsoft.office.outlook", "com.microsoft.office.outlook.MainActivity")
}
)
Do this...
context.startActivity(
Intent().apply {
action = Intent.ACTION_MAIN
addCategory(Intent.CATEGORY_LAUNCHER)
component = ComponentName(
outlookLaunchIntent?.component?.packageName,
outlookLaunchIntent?.component?.className
)
setPackage(outlookLaunchIntent.package)
}
)
Also, remember that getLaunchIntentForPackage and component can return null, so make sure you check for null values properly
I am relaying a suggestion from a couple of internal folks:
Please try to open the event using one of the following URLs:
ms-outlook://events/open?restid=%s&account=test#om.com (if you have a regular REST id)
ms-outlook://events/open?immutableid=%s&account=test#om.com (if you are using an immutable id)
Since immutable IDs are still in preview stage in Microsoft Graph, and customers should not use preview APIs in their production apps, I think option #1 applies to your case.
Please reply here if the URL works, or not, and if you have other related questions. I requested the couple of folks to keep an eye on this thread as well.
Well, i managed to open the outlook android application with the help of your code #Leo. As im not developping with Kotlin, ill post the JAVA code below :
Intent outlookLaunchIntent = context.getPackageManager().getLaunchIntentForPackage("com.microsoft.office.outlook");
if (outlookLaunchIntent != null) {
context.startActivity(outlookLaunchIntent );
}
Below code to open event/message in a web browser provided by webLink property of the graph API. (I only test for event and the url provided not working. Ill post a new issue on StackOverFlow for that but you already see the issue over there : https://github.com/microsoftgraph/microsoft-graph-docs/issues/4203
try {
Intent webIntent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse(calendarWebLink));
webIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(webIntent);
} catch (RuntimeException e) {
// The url is invalid, maybe missing http://
e.printStackTrace();
}
However im still stuck on the decicive goal of my widget item click which is to open the relative event/email in the Microsoft Outlook Android application.
Microsoft Outlook Android app contains widgets which can achieve what im looking for. So i wonder if it is possible to list its broadcast receivers.
The best thing i found is an old manifest for that app but it doesnt help me.

Hi may you try to open the event using one of the url:
ms-outlook://events/open?restid=%s&account=test#om.com (If the
user is having rest id)
ms-outlook://events/open?immutableid=%s&account=test#om.com (If
the user is having immutable id)
My Goal is here is to set my app as default launcher on Huawei devices.
1 - Explanations:
1.1 - Current situation:
I am already able to:
Check if my app is the default launcher
Display the 'launcher picker' (with the 'use once' / 'always' choice)
This all works fine.. except on Huawei devices!
From my point of view, Huawei's Android flavor does not properly 'honor' the "ACTION_MANAGE_DEFAULT_APPS_SETTINGS" intent action contract.
// this displays the list of default apps on all tested devices, except on Huawei devices!
// instead, it does display apps permissions, app links and apps'advanced settings
intent.setAction(Settings.ACTION_MANAGE_DEFAULT_APPS_SETTINGS);
activity.startActivity(intent);
As a B Plan, I am able to display the 'Applications & Notifications' settings 'page' using this:
String packageName = "com.android.settings";
String className = "Settings$AppAndNotificationDashboardActivity";
intent.setClassName(packageName, packageName + "." + className);
activity.startActivity(intent);
So the user can navigate from there, pressing this sequence of menu items:
-> Advanced Parameters ( expandable menu item : not present on tablet, and not sure it's present on phone)
-> Default Apps
-> Default Launcher
This requires 2 or 3 steps that I would like to avoid.
1.2 - This can be improved!
I found out that when the "-> Default Apps" menu item is selected, a (com.android.settings, .SubSettings) Intent (with extra) is launched but I was not able to make this works (permission denial).
But I installed Nova Launcher and it turns out it's able to display the "-> Default Apps" settings page on Huawei devices!
So the user land on a page where she/he only has to tap on "-> Default Launcher" then choose a default launcher: much easier.
2 - Questions:
As I think it's just not possible to display the 'Lancher Picker' on Huawei devices, here is my question:
How can I display the "-> Default Apps" settings page (image down here) on Huawei devices (like Nova Launcher does)?
Are they using another intent action on Huawei devices?
Thanks beforehand your help.
Yes on Huawei devices, Nova uses a different intent to open to the correct screen. I likely found this by using apktool on the Settings.apk pulled from a Huawei device and looking at the AndroidManifest.
Note that "com.android" is always a code smell as it means it's not part of the public API. Also this isn't even really "com.android" as it doesn't exist on AOSP and com.android.settings.PREFERRED_SETTINGS is purely a Huawei invention. It's very likely that some Huawei devices won't have this at all. It's also possible that in the future this intent might continue to work but not do what it currently does. So handle it carefully.
/* Some Huawei devices don't let us reset normally, handle it by opening preferred apps */
Intent preferredApps = new Intent("com.android.settings.PREFERRED_SETTINGS");
preferredApps.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
if (pm.resolveActivity(preferredApps, 0) != null) {
context.startActivity(preferredApps);
} else {
...
}
In fact, the accepted answer is not 100% correct, because it opens a general default apps chooser activity.
It works, but it's better to bring user right to the launcher chooser activity — it's com.google.android.permissioncontroller/com.android.packageinstaller.role.ui.HomeSettingsActivity (at least for the Android 10 Huawei Honors).
So, the correct code snippet is:
Intent()
.apply {
component = ComponentName("com.google.android.permissioncontroller", "com.android.packageinstaller.role.ui.HomeSettingsActivity")
addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK)
}
.takeIf {
packageManager.resolveActivity(it, 0) != null
}
?.let(context::startActivity)
I have an application. It is used to send and receive files using Bluetooth. My problem is, i wish to change the default location to store the file using Bluetooth at runtime. Can you tell me, Is there any possibility for this case?
It's not possible to configure it up to Android 4.1 Jelly Bean:
With the included stock bluetooth receiver you cannot change the location as of now, because it's hard coded. You need a 3rd party app like Bluetooth file transfer which might be configurable here.
In ./packages/apps/Bluetooth/src/com/android/bluetooth/opp/ you can see it.
Constants.java defines this:
public static final String DEFAULT_STORE_SUBDIR = "/bluetooth";
BluetoothOppReceiveFileInfo.java has no switch for the location:
File receiveFile = new File(uniqueFileName);
if (sDesiredStoragePath == null) {
sDesiredStoragePath = Environment.getExternalStorageDirectory().getPath() +
Constants.DEFAULT_STORE_SUBDIR;
}
The issue is that I need to install an apk(non market app) and for this, the user need to activate the unknown source setting, so i send him (if he didn't have it activated) to the settings so he can turn on the option, the issue is that i tested it in different phones and in samsung that option is on applications while in htcs phones is on security. i want send the user to that option but i don't know how to do it
I read about this and no one knows exactly how to do it
this is my code
int canInstallFromOtherSources = Settings.Secure.getInt(ctx2,Settings.Secure.INSTALL_NON_MARKET_APPS);
if(canInstallFromOtherSources == 0)
{
Intent intentSettings = new Intent();
intentSettings.setAction(android.provider.Settings.ACTION_APPLICATION_SETTINGS);
startActivity(intentSettings);
}
You can do it with the following line (changing to the corresponding action):
startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), REQUEST_CODE_ENABLE_LOCATION_PROVIDERS);
Check Android Settings documentation.
I think you should use ACTION_SECURITY_SETTINGS and one of ACTION_APPLICATION_SETTINGS or ACTION_APPLICATION_DEVELOPMENT_SETTINGS.
And here (line 304), you've got a working example of one of my apps: Tureame
Is there a way to start an Intent on the Kindle Fire that will cause the AppStore app to open and display all the apps for a certain developer? For instance, on a phone/tablet with the Android Market installed, I can do this:
Intent otherApps = new Intent(Intent.ACTION_VIEW,Uri.parse("market://search?q=pub:\"" + developerName + "\""));
activity.startActivity(otherApps);
And show all my apps in the Android Market. Can I do that with the Amazon App Store? If so, how? I've tried that Intent with other seemingly valid names (such as "ZeptoLab") and I don't get any filtering. It just drops me in the full unfiltered App Store. Looking up a specific app with "market://details?id=package.name" does seem to work.
From https://developer.amazon.com/help/faq.html#Marketing:
To point to your app for marketing purposes use the URL http://www.amazon.com/gp/mas/dl/android?p=packagename (where packagename is your app package name).
If you want to link to the list of all your applications on the Amazon Appstore use the URL http://www.amazon.com/gp/mas/dl/android?p=packagename&showAll=1.
e.g. http://www.amazon.com/gp/mas/dl/android?p=com.rovio.angrybirds&showAll=1
All this can be seen here: https://developer.amazon.com/sdk/in-app-purchasing/sample-code/deeplink.html
Update(deep linking):
amzn://apps/android?p=
Best way is to look at their website (or here), which currently states this :
search: amzn://apps/android?s=amazon%20mp3 or http://www.amazon.com/gp/mas/dl/android?s=amazon%20mp3
detail page using package name: amzn://apps/android?p=com.amazon.mp3 or http://www.amazon.com/gp/mas/dl/android?p=com.amazon.mp3
detail page using unique ID ("asin") : amzn://apps/android?asin=B004FRX0MY or http://www.amazon.com/gp/mas/dl/android?asin=B004FRX0MY
show all apps of the developer who made the app: amzn://apps/android?p=com.amazon.mp3&showAll=1 or http://www.amazon.com/gp/mas/dl/android?p=com.amazon.mp3&showAll=1
Amazon supports their own deep links now: https://developer.amazon.com/appsandservices/apis/earn/in-app-purchasing/docs/deeplink
E.g. you can start an intent with uri amzn://apps/android?p=my.package.name.
From - https://developer.amazon.com/help/tuabg.html
For in-app advertising or mobile browser based linking, please:
Use this link structure: http:// www.amazon.com/gp/mas/dl/android?p=com.example.package/ref=mas_pm_app_name
For a link that directs to a list of all of your apps within our U.S. store, please:
Use this link structure: http://www.amazon.com/gp/mas/dl/android?p=com.example.package&showAll=1
Now, you think amazon would have this correct on their own website, but the first part that I put in bold is wrong. This is what it should actually be:
http://www.amazon.com/gp/mas/dl/android?p=com.example.package&ref=mas_pm_app_name
Notice the & instead of the / between the package name and ref. Hopefully this helps some other people since this little detail wasted some of my time...
Here's the solution I came up with using the advice below from chiuki:
I added a boolean to one of my resource files that indicates whether or not the app is published in the Amazon AppStore or Android Market. Yeah, you have to change it whenever you publish your app, but think of it sort of like remembering to set debuggable to "false" when you publish. Put it on a check list. It goes like this:
In resource file:
<bool name="app_is_in_amazon_app_store">true< /bool>
In code:
public class SomeUtil
{
private static Boolean isInAmazonAppStore;
public static boolean isInAmazonAppStore(Activity activity)
{
if (isInAmazonAppStore == null)
{
isInAmazonAppStore = activity.getResources().getBoolean(R.bool.app_is_in_amazon_app_store) ;
}
return isInAmazonAppStore;
}
public static void startOtherMarketAppsActivity(Activity activity)
{
try
{
Intent otherApps = null;
if (isInAmazonAppStore(activity))
{
otherApps = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.amazon.com/gp/mas/dl/android?p=" + getPackageNameInAmazonAppStore(activity) + "&showAll=1"));
}
else
{
otherApps = new Intent(Intent.ACTION_VIEW,Uri.parse("market://search?q=pub:\"" + getAndroidDeveloperName(activity) + "\""));
}
activity.startActivity(otherApps);
}
catch(Exception ex){ /* error handling */}
}
